Strong Financial Performance:
- Mirum Pharmaceuticals reported total net product sales of $336.4 million for 2024, exceeding the upper end of the revised guidance range.

Pipeline Progress:
- The company expanded LIVMARLI's label with its approval for PFIC in the U.S. and Europe, and initiated the Phase III EXPAND study of LIVMARLI in broader settings of cholestatic pruritus.
- This progress is due to the positive interim results for volixibat in VISTAS PSC and VANTAGE PBC studies, which led to breakthrough designation in PBC, enhancing the company's pipeline potential.

Cash Flow and Financial Position:
- Mirum Pharmaceuticals achieved cash flow positivity in 2024 and ended the year with cash, cash equivalents, and investments of $293 million.
- This financial strength is attributed to the strong performance of its commercial medicines and a disciplined operating model, providing resources for upcoming pipeline catalysts.

Strategic Focus and Goals:
- The company's strategic priorities include global growth of commercial medicines, advancing its high-impact pipeline, and selectively pursuing product acquisition opportunities.
- These strategic initiatives are aimed at continued scientific and financial discipline to maintain a leading position in the rare disease market and enhance patient and shareholder value.
